GODFRIED LAURE, OF IIURON, DAKOTA TERRITORY, ASSIGNOR OF ONE- HALF TO T.J. MGBRIDE, OF VINNIPEG, CANADA.

STRAW OR HAY BURNING FURNAOE.

SPECIFICATION forming part of Letters Patent No. 392.8 l2, datedNovember 13, 1888.

Serial No. 269,311. (No model.)

To @ZZ whom it may concern.-

Be it known that I, GoDrRInD Linen, a citizen of the United States, anda resident of lrIuron, in the county of Beadle and Territory of Dakota,have invented. certain new and useful Improvements in Straw or I'IayBurning Furnaces; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figurel is a perspective view of myiniproved straw or hay burning` furnace. Fig. 2 is a vertical sectionalview of the same, and Fig. 3 is a cross-sectional view taken through thecenter of the partly-cylindrical shell or easing and the magazine.

Similar letters of reference denote corresponding parts in all thefigures.

My invention has relation to straw or hay burning furnaces, and itconsists in the im proved construction and combination of parts of thesame, as will be hereinafter set forth.

In the accompanying drawings, the letter A indicates the shell orcasing, partly cylindrical in form and provided at one edge with ahinged door, which, when closed, forms a cylindrical shell or casing.This shell or casing is supported upon a frame, B, constructed of sidepieces, C, and crossed lower pieces, D, the rearwardly-projecting one ofwhich is provided with a stop, E. A crescent-shaped sheet, F, is securedto the upper edge of this partly-cylindrical shell, and has projectingtherefrom two or more hot -air-condueting tubes, G, which extend eitherto rooms above the furnace or to rooms on the saine floor as thefurnace.

II indicates the smokcpipe for conducting the products of combustionfrom the straw magazine, and is attached to the upper ends of the frame,as more clearly shown in 1, and has its lower edge struclrup', as shownat I, and is provided at its intermediate forward portion with a hook,J. The top of the fuelmagazine slides vertically upon this pipe andconsists of the conical body formed with an annular flange, K, andanapertured downwardlyprojecting edge, L, and provided with handles M, andnear its upper portion with a notched plate, N. A collar, O, is securedto the upper inner portion of this cover and prevents the said cover,when sliding` upon the pipe, from playing laterally thereon, which wouldcause the cover, when being adjusted, to bind upon the pipe.

T denotes the straw-burning magazine, the peculiar construction of whichI make no claim for in this application. This magazine is provided withhandles U, doors V and XV, respectively, through which the fuel may belighted and attended to, and with a draft-cup, X, communicating with aperforated drafttube, Y, in the bottom of the magazine. This magazineiainclosed within the partlyeylinl drical shell or easing and issupported upon the cross-pieees of the frame and abuts against the stopE, which prevents the magazine from being placed too far in the rear ofthe shell or casing.

The operation of my invention is as follows: After the magazine has beenfilled with fuel (straw or hay) it is placed within the casing, and thecover is lowered to fit with its downwardlyprojecting edge therein or isadjusted vertically, as may be desired, by means of the hooks upon thestove-pipe and the notched plate of the cover, so as to regulate thedraft by means of the apertures in the downwardlyprojecting edge ofthecover. The fuel is now lighted through the upper door of the maga` zine,and the draft-cup in the bottom thereof is regulated by means of asliding damper, X', (shown only in Fig. 2,) in the saine manner as isshown and described in my former application, iiled December 27, 1887,Serial No. 259,066, so as to cause the desired draft. The door oftheshell or casing is provided with circular apertures Z, which areencircled by annular flanges Z', which impinge upon the magazine andprevent thehot air from escaping through the apertures of the door.Through two of these apertures project one of the handles and thedraft-cup of the magazine, while the other apertures permit the doors inthe magazine to be opened and the fire attended to. The cold air betweenthe magazine and the easing or shell becomes heated and ascends ICO 2segale What I do claim, and desire to secure by Letters Patent, is-

1. The combination, with a frame, substantially as herein described, apartlycylindrical shell or casing, and a smoke-pipe supported by theupper ends of said frame, of a removable magazine and an adjustable top.

2. The combination, with a frame, substantially as herein described, astop upon said frame, a partly-cylindrical shell or casing, acrescent-shaped top sheet secured to the upper edge of said shell orcasing, hot-air tubes in the said top piece and communicating with theinterior of the easing, and a hinged door, of a stove-pipe supported bythe upper ends of said frame, and an adjustable cover secured thereon.

3. The combination,with the frame, substantially as described, of apartly cylindrical shell supported thereon, a crescent-shaped top sheetsecured to the upper edge of said frame, hot-air-eonducting tubessecured in said top piece and communicating with the interior of theshell or casing, and a hinged door secured in one of the side edges ofthe shell or casing, a removable straw-magazine, a vertically-adjustabletopand a smoke-pipe.

4. The combination of a frame, substantially as described, a smoke-pipesecured to the upper end of the same and provided with a struck-up lowerend, and a hook upon said smoke-pipe, with a conical top having handlesattached thereto, a notched strip secured to its upper edge, and acollar secured to the interior top portion thereof, whereby the saidcover is retained against lateral movement when being adjusted.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
